Iron Ore Agglomeration Technologies

2021/12/20Until the 1950s of the last century, the oxidized iron ores that were loaded into the blast furnace had granulometries within 10 and 120 mm. However, the depletion of high-grade iron ore sources has made necessary the utilization of concentration processes with the purpose of enriching the iron ore. Because of these processes, a fine granulometry is produced, and

Pima County Arizona Gold Production – Western Mining History

The Ajo district is in western Pima County, 125 miles west of Tucson. Small-scale mining of copper deposits was done by Spaniards and Mexicans as early as 1750, and Indians used the red oxides and green carbonates from the Sierra Del Ajo to paint their bodies. Americans entered the area after the Gadsden Purchase of 1853 and located the Ajo mine.
